title: Synthesis of amidrazones from 2-ethoxycarbonyl-4H-3,1-benzoxazin-4-one.
abstract: Hydrazine, phenylhydrazine and carboxylic acid hydrazides underwent an addition reaction to the 1,2 double bond of 2-ethoxycarbonyl-4H-3, 1-benzoxazin-4-one with ring opening to give oxalamidrazone derivatives. Preliminary screening of these amidrazones showed that some of the synthesized compounds exhibited antitubercular activity.
